Critical Review of Control Strategies for Switched Reluctance Motor Employed in Electric Vehicle

Abstract

This paper presents a critical review of control strategies for switched reluctance motor employed in electric vehicle. The survey is carried out on various control strategies namely average torque control, instantaneous torque, torque sharing and direct instantaneous torque control. The purpose of the survey is to identify the capability of control strategies in terms of speed and torque of SRM for electric vehicle application. The preliminary observation from the study is that, SRM have high torque ripples and it is severe during commutation between the adjacent phases. Further, it also leads to high acoustic noise, vibration and harshness of the electric vehicle system. In view of this, there is need to develop an appropriate control method to overcome the said problems of SRM drive employed in EVs.
